1 Claim.

This invention relates to closures for collapsible tube containers used in the sale and dispensing of dental, shaving, cold creams and other similar semi-liquid materials, and has for the primary object the provision of a device of this character which will permit easy and quick removal of the closure or cap from the discharge neck of the container without becoming fully detached from said container so as to prevent loss or dropping of the cap when removed or in the act of removing or replacing thereof on the container.

With these and other objects in view, the invention consists in certain novel features of construction; combination and arrangement of parts to be hereinafter more fully described and claimed. I v

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a fragmentary side elevation illuse trating a collapsible tube or container equipped with a closure constructed in accordance with my invention.

Figure 2 is a top plan view partly in section illustrating the same. I

Figure 3 is a perspective view illustrating the closure or cap mounting.

Figure 4 is a vertical sectional view illustrating the cap or closure.

Referring in detail to the drawing, the numeral 5 indicates a collapsible tube or container having the usual screw threaded discharge neck on which is threaded a closure or cap 6 forming a part of the present invention and consisting. of

a substantially cone-shaped body 'l having a screw threaded socket 3 to permit the body to be threaded onto the neck of the container or tube. The body 7 adjacent the base thereof is provided with an annular groove 9' to receive a mounting l consisting of a resilient split ring ll having the ends thereof bent to form parallel arms l2 and the latter having portions thereof bent to form L-shaped portions 13 arranged in spaced opposed relation.

The resilient ring ll may be expanded'to' permit said ring to be passed over the body 1 of the.

cap or closure and to become seated in the groove cap or closure rotatably connected thereto. The L-shaped portions l3 of the arms l2 provide hinge pintles to be received in sockets M of a lug l formed on the container or tube 5.

Through the use of the portions l3 and the lug l5 and its sockets the mounting becomes hinged on the tube or container. The cap or closure thenmay be swung into engagement with the neck and threaded thereon in the usual way. A portion of the body I of the closure or cap is provided with serrations to provide a knurled surface to permit a person to readily grip the cap or closure. After the cap or closure has been threaded on the neck of the container or tubeit may be swung laterally of the latter still remain- I ing attached to the containerortube and consequently preventing the loss thereof.

It is believed that the foregoing description, when taken in connection with the drawing, will fully set forth the construction and advantages of this invention to those skilled in the art to which such a device relates, so that further detailed description will not be required.

What is claimed is: g A closure for the neck of a collapsible tube comprising an internally threaded tubular cap for turning on and off said neck and provided with a circumferential groove in the base end thereof, an apertured lug adapted to be carried by the neck end of said tube, and a single piece cap holder of resilient wire comprising a ring at one end thereof loosely fitting in said groove to provide for free turning of said cap relative to the holder, said ring being split for spreading to said ends also including stop portions at right angles to said arms and trunnions for engaging the neck end ofthe tube to limit swinging of the holder in one direction. a

TED HARRISON.
